Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns flowerpots.

``Prior art'' Conventionally, a perforated upright tube was provided on the inner surface of a flowerpot, a capillary material such as a sponge or hydrophilic string was filled in the tube, and a hydrophilic string connected to the capillary material was hung in the water tank below the bottom plate. There was an irrigation device that absorbed water from the aquarium into the flower pot by capillary action (Utility Model No. 59-50246,
Utsukai No. 60-190242).

Such a flower pot was applied to a small flower pot equipped with one perforated upright tube, and exhibited an automatic irrigation effect. However, when the plants and flower pots are large, the above-mentioned perforated upright tubes often cause irrigation locations to be unevenly distributed, the amount of water to be irrigated to be uneven both vertically and horizontally, and the area of irrigation per perforated upright tube is large. The amount of irrigation was excessive, and there was a risk of root rot in the large plants.

``Problems to be solved by the invention'' This invention attempts to obtain a flower pot that is free from root rot by suppressing the increase and unevenness of watering in an automatic capillary watering device for flower pots.

``Means for solving the problem'' This idea involves placing a perforated tube on the side close to the inner surface of a synthetic resin pot from the upper edge of the pot to the bottom plate, and absorbing water from the capillary material inserted into the tube. A hydrophilic cord is hung below the bottom plate, and a water tank is placed under the bottom plate.
The flower pot is constructed by having countless fine holes formed in the side plate of the pot, which are densely formed near the upright tube and loosely formed in the isolated part.

"Function" Therefore, when the soil 18 is stored in the synthetic resin pot 1, the water 17 is stored in the water tank 6, and the plants 26 are planted,
Water is absorbed from the water-absorbing hydrophilic string 4 into the capillary material 3 in the perforated upright tube 2 by capillary phenomenon, and the capillary material 3 becomes a dedicated path for water to rise, allowing the water to reach the upper end of the upright tube 2. raise. Water can then be automatically applied to the inside of the soil 18 from the through hole 16 of the upright tube 2 by capillary action. The water in the soil 18 is supplied from the perforated upright tube 2, but a portion of it passes through the dense pores 7 near the tube 2 and emanates to the outside of the pot 1 in a relatively large amount. A relatively small amount of water that reaches the side plate 9 isolated from the side plate 9 emanates from the rough and fine holes 8 of the same side plate 9, and water rarely accumulates on the inner surface of the side plate 9.

"Example" A net 1 is placed on the porous bottom plate 5 of a cylindrical synthetic resin pot 1.
0 is placed, the side plate 9 is extended downward to form an aquarium storage box 11, and a synthetic resin aquarium 6 is inserted directly under the bottom plate 5 through an opening 12 formed in the box 11. It is. A plurality of through holes 13 into which the lower ends of the perforated upright tubes 2 are fitted are bored in the bottom plate 5 at positions close to the side plates 9. are arranged at predetermined intervals. Inside these tubes 2, there is a core tube 14 in which a capillary material 3 made of sponge, hydrophilic string 3', etc. is arranged inside and outside.
The head 15 of the tube 14 is engaged with the upper end of the upright tube 2, and the vertical holes 16 bored on both sides of the tube 2 are closed with the core tube 14 (Fig. 4). Alternatively, the amount of water can be adjusted by exposing the hydrophilic string 3' to the long hole 16 (FIG. 5). At the lower end of the capillary material 3, a water-absorbing hydrophilic string 4 hangs down from the through hole 13 into the water tank 6 below, absorbs the water 17 in the water tank 6 by capillary action, and further enters the capillary material 3. The capillary material 3 serves as a dedicated path for water to rise, allowing water to be applied from the longitudinal hole 16 into the soil 18 by capillary action. A countless number of fine through holes 7 and 8 are bored in the side plate 9 of the pot 1, and the fine through holes 7 are closely bored in the vicinity of the upright tube 2, and the distance between the tubes 2 and 2 is increased. In the middle of the section, that is, in the isolation section, fine holes 8 are roughly bored, and a relatively large amount of water in the soil 18 flows out from the fine holes 7 near the upright tube 2 due to capillary action. In the isolated part, a relatively small amount of water is released from the small through hole 8 to the outside. In addition, what is indicated by 19 in the figure is the above-mentioned standing tube 2.
20 is a rotation position mark, 21 is a ventilation hole drilled in the aquarium housing box 11, and 22 is a hydrophilic string 4 for water absorption.
23 is a guide, 24 is a knob, and 25 is a scale for the water tank 6.

``Effects'' Since the present invention is constructed as described above, the capillary material 3 in the perforated upright tube 2 inside the flower pot forms a dedicated passage for water to rise, allowing the water to rise to the upper edge of the flower pot, causing unevenness in the vertical direction. In addition, water accumulated on the inner surface of the side plate near the dedicated passage can be sufficiently dissipated through the dense pores 7, preventing uneven irrigation in the lateral direction, improving air permeability, and preventing root rot. It can also be applied to large flower pots.
